Tacit renewal is one of the most important mechanisms in the field of lease agreements, often raising questions among both landlords and tenants. It is a legal concept that takes effect automatically, extending the term of a lease agreement once its initial term has expired, without the need for a new express agreement between the parties.
Its application can significantly affect the rights and obligations of both parties, influencing aspects such as the lease term, the rent amount, and even the landlord’s ability to reclaim the property.
In this updated guide, we’ll analyze in detail what the law says, what requirements must be met, how long this arrangement can last, and what consequences it has for landlords and tenants. We’ll also provide practical advice on how to avoid tacit renewal when it’s not desired.
Tacit renewal is a legal concept that allows for the automatic extension of a lease agreement once its initial term has ended, provided that neither party expresses a desire to terminate it.
Unlike a voluntary extension, in which both parties agree to renew the contract, tacit renewal takes effect without the need for a new express agreement. It is sufficient for the tenant to continue occupying the property and paying rent, and for the landlord to accept this, for the lease to be renewed under the same conditions or with the variations established by law.

In Spain, tacit renewal is regulated by Article 1566 of the Civil Code, which states that: “Upon termination of the lease, if the tenant continues to occupy the leased property for more than fifteen days with the landlord’s acquiescence, the lease shall be deemed renewed for the term specified in the preceding articles, and so on.”
In addition, the Urban Lease Law (LAU) also addresses this concept in Article 9, which applies to residential leases. According to this provision, if the tenant remains in the property after the term has ended and the landlord does not object, the lease is automatically renewed for annual terms (in residential leases) or as initially agreed (in leases for non-residential use).
The lease agreement must have reached its original expiration date without an express renewal through a new agreement between the parties. This applies both to fixed-term leases (for example, one year) and to those without a fixed term but where the landlord decides to terminate the agreement.
The tenant must continue to occupy the residence or commercial space after the contract’s expiration date, thereby demonstrating their intention to remain. This continued use is primarily demonstrated by the payment and acceptance of rent in the months following the expiration date, by maintaining utilities (electricity, water, etc.) in the tenant’s name, and by the tenant’s lack of intention to vacate the property.
The landlord must not actively oppose the continuation of the lease. This tacit consent is presumed when the landlord collects rent for the period following the lease’s expiration, when the landlord does not initiate legal action to reclaim the property (such as an eviction lawsuit), and when the landlord does not communicate in writing their decision not to renew the lease before its expiration.
Some leases include clauses that explicitly exclude tacit renewal, thereby establishing that the lease will definitively end on a specific date without the possibility of automatic renewal. In these cases, the tenant’s continued occupancy of the property could be considered unlawful occupation rather than tacit renewal.
In residential lease agreements, it applies when the tenant continues to live in the property after the initial term expires, or if the landlord fails to notify the tenant of their intention not to renew the lease with the legally required advance notice (typically 30 days for residential leases).
For leases for non-residential use (commercial spaces, offices, etc.), it applies if the tenant continues to conduct their business on the premises and the landlord does not demand their eviction, and when there is no automatic termination clause at the end of the term.
In verbal leases or those without a defined term, if the tenant has been occupying the property for some time without a written lease and the landlord accepts the rent payments, it may be understood that there is an implied lease that is renewable annually.
This does not apply when the landlord provides reliable notice of their intention not to renew (via certified fax, email with acknowledgment of receipt, etc.), if there is an express clause in the lease prohibiting automatic renewal, or in cases of eviction due to the landlord’s need (such as reclaiming the property for personal use).

The duration of tacit renewal varies depending on the type of lease agreement. In residential lease agreements, according to Article 9 of the LAU, the lease is renewed for successive annual terms as long as neither party expresses a desire to terminate it, which means that, in theory, the lease could continue indefinitely if the landlord does not take steps to terminate it.
For leases for non-residential use (commercial spaces, warehouses, etc.), the terms of the original lease govern; if there is no express agreement, the Civil Code (Art. 1566) establishes that the renewal will be for years or months, depending on the frequency of rent payments (for example, if rent is paid monthly, the renewal will be month-to-month).
There is no maximum limit on the number of years, but the landlord may always terminate the lease with the required legal notice. In practice, many tacitly renewed leases last between 1 and 5 years before either party decides to terminate them.
When does tacit renewal occur? When the initial lease agreement ends (and, for residential properties, the tacit extension under the LAU also ends) and the tenant remains in the property for more than fifteen days with the landlord’s consent, without the landlord having previously demanded that the tenant vacate the premises. How long does the new lease last? Article 1566 refers to Articles 1577 and 1581 of the Civil Code, so the duration depends on how the rent is paid. If rent is paid monthly, the new lease is deemed to be for months; if paid annually, for years. This is the prevailing interpretation of the courts, although there are rulings with different criteria, so it is advisable to review each case individually.
How long can a lease be tacitly renewed? There is no limit: the periods continue to roll over as long as neither party decides to terminate it. And what happens when a tenant has been there for more than 10 years? Length of tenancy, by itself, does not entitle the tenant to remain indefinitely or to acquire ownership of the property. A person occupying a property as a tenant does not possess it as an owner, and that is an essential requirement for adverse possession. The exception is “old-style” lease agreements, signed before May 9, 1985, which follow their own transitional rules.
Although they are often used interchangeably, tacit extension and tacit renewal are not the same thing. What does tacit renewal of a lease entail? Once the lease and all its legal extensions have expired, the tenant remains in the dwelling with the landlord’s consent, and a new lease relationship is established. Where is tacit renewal regulated? In Article 1566 of the Civil Code, which applies to residential leases on a supplementary basis through Article 4.2 of the LAU. In everyday language, the term “tacit renewal” is used to refer to both situations, because in both cases the lease continues without anyone signing anything. But the legal distinction has consequences.
For residential leases signed on or after March 6, 2019, the lease term lasts at least five years (seven if the landlord is a company) due to the mandatory extensions under Article 9 of the LAU. When that term expires, Article 10 comes into play. If neither party notifies the other that they do not wish to renew, the lease is extended on an annual basis for up to three additional years. The landlord must give at least four months’ notice, and the tenant two months’ notice. This is how tacit renewal works: it is the same lease, under the same terms, and the tenant may move out by giving one month’s notice at the end of each year.
The key difference from tacit extension is, therefore, the order: first, the extension under the LAU must expire, and only then can tacit renewal occur.
For the tenant, tacit renewal entails the right to remain in the dwelling without the need for a new lease, the maintenance of the original terms and conditions—except for rent adjustments based on the CPI or as agreed—and protection against abrupt evictions, since the landlord must comply with the required notice periods.
For the landlord, it becomes more difficult to reclaim the property if they do not act with due notice; they have the option to adjust the rent as agreed in the initial lease (although in some cases the LAU limits increases), and they run the risk that the tenant may acquire long-term rights, especially in primary residences.
The tax and registration implications are that a tacitly renewed lease does not need to be registered with the Property Registry but remains valid, and the rent received must be reported on the landlord’s personal income tax return.
If the landlord does not wish for the lease to be tacitly renewed, they must give advance notice of non-renewal by sending a certified notice (certified fax, email with read receipt) at least 30 days before the expiration date (for residential properties). For commercial properties, the notice period may be longer (check the original lease agreement).
The landlord must not accept payments after the expiration date; if the tenant attempts to pay after the termination date, the landlord must refuse the payment or accept it “with reservations,” indicating that it does not imply an extension.
You may initiate eviction proceedings if necessary; if the tenant does not vacate the property, the landlord may file an eviction lawsuit based on the expiration of the lease.
The original lease agreement may stipulate that there will be no tacit renewal, thereby requiring the tenant to vacate the property upon expiration.
The guidelines above for avoiding tacit renewal coexist this year with a temporary measure that can extend the lease even if the landlord does not wish to renew it. Its implementation has been rocky, so it is advisable to read this section with the date in mind (November 2026). In March, an initial extraordinary two-year extension was approved, but the full Congress rejected it on April 28. In the fall, history repeated itself: Congress repealed the housing decrees on October 2, and the government re-approved the measures as Royal Decree-Laws 28/2026 and 29/2026, published in the Official State Gazette (BOE) on October 7.
In reality, it is not a law passed by Parliament, but rather a Royal Decree-Law issued by the government. The new decree, effective as of October 8, 2026, allows for an extraordinary extension of up to two years—in annual increments—for primary residence lease agreements. During this extension, the same terms and conditions of the current contract remain in effect. Furthermore, for leases where the rent is due for adjustment between the decree’s effective date and December 31, 2027, the increase cannot exceed 2% if no agreement is reached, and no increase applies if the rent already exceeds the reference price index limit.
Tenants with a lease in effect as of October 8, 2026, whose mandatory extension expires before December 31, 2028, as well as those whose tacit extension or tacit renewal expires. The tenant must be current on rent payments, and this requirement applies to all landlords. Exceptions apply if the parties have agreed to different terms or a new lease, or if the landlord has notified the tenant within the timeframes established by the LAU that they need the property for themselves or their family members. This extension does not apply in addition to the extension for areas with a tight residential housing market, which takes precedence.
Since Parliament has been dissolved due to the November 29 elections, ratification falls to the Permanent Commission of Congress, which plans to vote on the two decrees on November 12. The PNV has announced that it will support the decree containing the bulk of the measures (Decree 29/2026) and will vote against Decree 28/2026. The latter would take effect on November 15, providing for extensions of five or seven years, a six-month notice period, and compensation for the tenant if the lease is not renewed. If a decree is not ratified, its provisions lapse upon publication of the agreement, with no retroactive effect on what has already been implemented. Therefore, before assuming an extension is in effect, it is advisable to check the current status in the Official State Gazette (BOE).

Tacit renewal is a legal mechanism that protects both tenants and landlords, allowing the lease to continue without additional paperwork. However, it’s essential to understand its requirements and consequences to avoid conflicts.
If you’re a landlord and don’t want to renew the lease, give notice in a timely manner; if you’re a tenant, make sure your continued occupancy doesn’t lead to disagreements. If in doubt, consult a specialized attorney.
